[PATCH] powerpc64: fix spinlock recursion in native_hpte_clear

native_hpte_clear has a spinlock recursion problem with the native_tlbie_lock
being called twice, once in native_hpte_clear() and once within tlbie().
Fix the problem by changing the call to tlbie() in native_hpte_clear() to
__tlbie(). It still supports only 4k pages for now.
